CVE-2024-13645Network attack vector

Conditional code execution via arbitrary object instantiation

Published Apr 4, 2025 · Updated Apr 8, 2026

PHP object instantiation in tagDiv Composer 5.3 and earlier allows remote attackers to instantiate arbitrary classes via the module parameter. The module parameter is accepted as a class-selection value and used to instantiate a PHP object without restricting the selected class. No known POP chain exists in the plugin itself; code execution, file deletion, or data retrieval requires a compatible chain from another installed plugin or theme.
